And of them is he who hearkens to you, and We have cast veils over their hearts lest they understand it and a heaviness into their ears; and even if they see every sign they will not believe in it; so much so that when they come to you they only dispute with you; those who disbelieve say: This is naught but the stories of the ancients.

And certainly We have created for hell many of the jinn and the men; they have hearts with which they do not understand, and they have eyes with which they do not see, and they have ears with which they do not hear; they are as cattle, nay, they are in worse errors; these are the heedless ones.

Have they feet with which they walk, or have they hands with which they hold, or have they eyes with which they see, or have they ears with which they hear? Say: Call your associates, then make a struggle (to prevail) against me and give me no respite.

Have they not travelled in the land so that they should have hearts with which to understand, or ears with which to hear? For surely it is not the eyes that are blind, but blind are the hearts which are in the breasts.

And when Our communications are recited to him, he turns back proudly, as if he had not heard them, as though in his ears were a heaviness, therefore announce to him a painful chastisement.
